The Osborne 1

List Price: US $1,795

Release Date: June 1981

Released in June 1981 by the Osborne Computer Corporation, the Osborne 1 is considered to be the first true portable, full-featured computer. It includes all the components required to be a completely useful and operational computer system:

  • two built-in floppy drives which hold 91K of data each, with floppy disk storage compartments
  • a detachable full-size keyboard with numeric keypad
  • a built-in, albeit small, monochrome CRT monitor.
  • runs the CP/M Operating System, the most popular OS at the time.

What makes it portable, or more often described as luggable, is that everything is in one package, easily transported from one location to another by simply unplugging the power, attaching the keyboard to the front of the system, and being on your way. The leather carrying handle on the back is a classy touch.
